A proposal to travel at the speed of light: Travel as Light.
By having a machine scan a human and send his information via a computer encoded ensamble of photons, a human can send not only what he looks like, but his genetic makeup, every cell in his body, and every last bit of what he is in a strand of photons that are ordered in such a way that a computer can recieve them far away. The computer would decode this strand of light and with another machine far away, reassemble the human at the new location (the person that opted to be transported via beams of photons would be discarded of to preserve the theme of someone traveling and not just duplicating himself). The machine would have to be very precise and able to scan every last detail about a person.
The person would have therefore (seemed to have) traveled at the speed of light, but actually his information was transported at the speed of light. This could possibly be the fastest mode of transportation that we have in the future.
